MOSSES FROM TARBERT IN HARRIS in 



The section of the nerve near the base presents much 

 the appearance of that of C. Hunti, described in the " Annals " 

 for April 1899, although the cell-formation near the base is 

 not so open behind as in the latter, while the nerve is much 

 broader relatively, and the areolation of the pagina near the 

 base much smaller, etc. I have not detected in C. Hunti 

 any of the blunt serratures on the back of the leaf- 

 serratures which must surely be distinct from the posterior 

 bulging cells. 



Cainpylopus atrovirens grows in great luxuriance and 

 often attains a great size in this district. Two forms are 

 so peculiar that I am tempted to give distinction to them. 



The first, which may be called var. incurvatns, is densely 

 tufted, deep green above, brownish black or even almost 

 black below ; apical leaves and others lower down have 

 cucullate, blunt apices, and only a few leaves with short 

 hair-points intermingled down the stem. The structure 

 of the nerve, in this variety, does not differ from that of 

 the normal form. 



The second, to which the name var. flexilis has already 

 been given, has quite a different habit from the typical form. 

 The tufts are very close and dense, large, and often from 

 4 to 6 inches long ; stems closely compacted, yet readily 

 delapsing, slender and flexile ; the leaves are rather closely 

 set, each having a short, stiff, denticulate point, which is 

 permanent or at least does not easily become detached as in 

 the normal form. The constitution of the nerve is not 

 different from that of the typical form. This moss has 

 several of the peculiarities of C. brcvipilus. 



Grimmia sublurida, described several years ago in the 

 Scottish Naturalist, was found in great plenty. It presents 

 various aspects, from a lurid green to a somewhat yellowish 

 green, but all in dense compact tufts, about one inch or less 

 in height, and quite unlike any form of Gr. heterostic/ta, to 

 which Dr. Braithwaite refers it, and characterises it as 

 merely a " dwarf starved form " a very unlikely condition 

 in such a moist climate. 



Another Grimmia, closely allied to Gr. sublurida, if 

 indeed they can be separated, is tolerably common. Its 

 tufts are as dense, but they have a softer feel, and the stems
